structure is ineffective during the treatment oi the articles and that dur ng-such treatment the spindle S is rotated at desired speed by clutching the pulley 10 to this spindle means of the clutch mechanism 13.

In conjunction with this mechanism, we have provided a p a-rtrble casing member embodying units 24L and 25 which are hinged to the vertical shaft 26 extend ng between the base 1 and the cross piece at;

at its upper end with the exception of semicircular'cut out portions 27 and 28 that are sufiiciently large to permit free lateral play of the spindle 8 during the treating operation. The partible members 2a and 25 are held in closed relation by means of a latch structure 29.

Figures 3 and 4 illustrate a modified form of apparatus which is made possible by the novel principles of our apparatus't'or removing the excess fluid from the galvanized articles. In the first place, it will be apparent that our idea of using a suspended spinning basket makes it possible to utilize this suspending apparatus as a means for dipping he articles into the galvanizing fluid as well as for spinning these articles to remove the excess of such fiuid- Furthermore, these steps fit naturally into a simple and eiiicient method for treating these articles by a con- "tinuous series of steps from the time they leave the pickling bath untll they are delivered in finished condition to a storage room, all of which may beaccomplished automati' cally. r 1

Thus, after the pickling process is completed. the articles may be transferred automatically or otherwise into a seriesot baskets of the type shown in Figures 1 and 2. Such a series of baskets are shown in Fig ure 3 as being mounted upon an endless con-.

veyer 30 which successively feeds these haskets to a. point A. At this point A, the handle of the basket is placed upon the hook 15 of the spindle 8, either automatically or manually.

In the form of apparatus shown in Figures 3 and 4:, the spindle 8 is vertically slidable on its journals and is provided upon its upper end with a swivel 31 that is connected by means of a hoist rope 32 and suitable pulleys 33 and 34 to a pivoted bracket 35. This bracket 35 is pivoted as at-36 in such a position that its outer and upper end is capable of a lateral and arcuate movement from the point A where it receives the spinning basket hookl5 of the spindle 8, this spindle is preferably in such a position of elevation that thebasket is above the level i of the top-of the gal-van-izing kettle E. It is also at one side of this-galvanizing kettle, as-shown in F i gure 3. Immediately upon receipt, the member 35 is swung upon'its pivot until the basket is directly over the galvanizing kettle and within the confines of a metal guard 37 that may bepartible as in the structure shownin Figure Qand that may also be closed either automatically or manually by the movement of the spindle carrying basket into position above the galvanizing kettle.

As soon as this basket is in proper position above thelgalvanizing kettle, the hoist rope 32 is manipulated either automatically or manually to bring about immersion o-f the basket of articles in the bath of galvanizing 'fiuid. After this immersion has been satisfactorily accomplished, the hoist rope 32 is again manipulated, either automatically or manually, to raise the basket above the level of the galvanizing bath and into the confines of the metal guard 37. When in this position, the pulley 10 is clutchedto the spinning shaft 8 as the spinning of-the basket causes a removal of the surface galvanizing fluid from the articles within the basket. As soon as this is accomplished, the metal guard 37 is opened upon its opposite side, either automatically or manually, and. the basket is swung to position 13. At this position, the basket is dumped, either automatically or manually, so as to deliver the finished articles upon the trough or track C, whence they travel by gravity or otherwise to the storage room D.

The spinning of the'articles above the bath of hot metal and Within a hood, such as the metal guard 37, thereover produces certain distinct advantages. In the first place, the time period between removal from the bath and commencement of spinning is greatly decreased. Likewise, this spinning is effected under subjection to the currents of hot air moving upwardly from this hot metal bath and this serves to simplify the removal of the excess material in that it both minimizes the time period required for spinning and the degree of centrifugal force necessary to re- -move the surface material.

- the axis of rotation of the basket with its contents are a substantially common axis which 7 passes automatically through the center of gravity of the rotating mass; F orinstance,

is free from any tendency of the basket to tip over. With this suspension principle, the center of gravity of the basket and its contents, when being suspended from the hook, does not lie'on the projected axis of the spindle when the basket is stationary, the

combined action of centrifugal force, gravity I and the gyroscopic action of the device will tend to pull the center of gravity of the whirling basket into alignment with the center of rotation under the stresses developed when r0 tated.

This principle of supporting by suspension makes possible the effective removal of excess galvanizing fluid with a minimum of vibra tion of the apparatus utilized. Thus,'there is ensured a smooth operation and maximum longevity of the apparatus.

Another important aspect of ourinvention arises from the fact that our suspending spindle can. be utilized for dipping of the basket of articles in the galvanizing bath and removal'from such bath withoutdetaching such basket fromits hook during such dipping and removal and during spinning.

Likewise, this mechanism greatly facilitates the provision of a mechanism for receiving the basket of articles, transferring it to the bath of galvanizing material, removing 1t from this bath, spinning to remove the ex cess fluid and dumping the finished product" onto a means for delivering'such finished articles intoa storage compartment. Various other obvious advantages flow from the construction described.

A still further important feature of our invention arises from the fact that we have provided a receptacle of such construction that the material to be galvanized will be confined to a-space within the receptacle that is substantially removed from the center of therecept-acle.v In other Words, the material to be galvanized will be confined to the greater circumferences of the receptacle. It is well known that-the further removed the articles are from the center of rotation, the greater the centrifugal action on the articles will be. Thus, with the articles confined to the great- 1.
